BOTTLE-VALVE.

Specification of Letters Patent.

Application filed December 6, 1916, Serial No. 135,343. Renewed February 1, 1919. Serial No. 274,566.

To all whom it may concern:

Be it known that I, GILBERT JACKSON, a citizen of the United States, residing at New York, in the borough of Manhattan, city of New York, and State of New York, have invented certain new and useful Improvements in Bottle-Valves, of which the following is a specification.

My invention relates to bottle valves, and more particularly that class which has for its object to prevent the refilling of bottles after they have been once emptied, and contemplates certain improvements in the construction of the same, as will be more definitely pointed out and claimed hereinafter, reference being had to the accompanying drawings, in which Figure 1 1s a central vertical sectional view of my improved device located in a bottle neck.

Fig. 2 is a transverse section, taken on the line II-II of Fi 1.

Fig. 3 is a View 0% the various parts of the bottle valve, shown separated and in perspective.

Fig. 4 is a vertical sectional view of a modified form of the bottle valve.

Similar numerals of reference denote corresponding parts in the several views.

In the said drawing, the reference numeral 1 denotes the neck of an ordinary bottle, such as a whisky bottle, in whichis disposed a partial closure 2 forming a valve seat ,3, upon which is adapted to seat the lower curved end 1 of a hollow valve member 5, said valve seat and valve member being formed of some porous material of a character which will cause said valve and seat, when the parts are wet, to stick to each other against relative movement when the bottle is shaken, and yet will permit said valve to leave its seat when the bottle is inverted and the pressure of the liquid is exerted thereon. The valve member 5 is closed at its upper end, preferably by a cork piece 6, into a central aperture in which fits the stem 7 of a disk-8, which is of even diameter with the exterior diameter of the valve member 5, and is for a purpose hereinafter to be described. Fitted to the top of the partial closure 2 is a casing 9, of porcelain, or other suitable material, provided with a discharge orifice 10, and below said orifice being enlarged interiorly to correspond with the interior diameter of the upper end of the partial closure 2, the interior of the upper end of the casing 9 being screwthreaded at 11 to. receive similar screwthreads 12 on a plug 13 screwed thereinto, the screw-threaded portion of said plug being mutilated'at intervals longitudinally at 14 to provide liquid passages therearound, the upper end of said plug being formed with projections 15 spacing it from the upper interior wall of the casing, whereby a free passage of liquid in the bottle is permitted therearound. Interposed between the top of the valve member 5 and the lower concaved surface 16 of the plug 13 is a ball 17 of glass or other suitable material, an appreciable space being left between the two when the ball is resting upon the cap 8, said construction, when the bottle is inverted, permitting the valve member 5, when the ball 17 drops into the, cup-shaped portion 16 of the plug 13, to leave its seat 3 and permit the flow of liquid from the interior of the bottle past the same.

In operation, with the bottle in the vertical position shown in Fig. 1, the ball 17 rests upon the valve member 5 maintaining it in its closed position, but when the bottle is invented the ball 17 drops into the seat 16, thus releasing the valve 5 and permitting the flow of liquid past the same, and, through the recesses 1 of the plug 13', to the discharge opening 10 of the casing 9, said valve member being spaced from the inner Wall of the partial closure 2 by the ribs or fins 18. Under 01'- dinary circumstances this construction most effectually will prevent therefilling of the bottle through the pouring of liquid in the neck 10. when the bottle is in the vertical position. Nor will it be possible to cause the liquid to flow into the bottle by agitating the bottle vertically, as the semi-porous character of the partial closure 2 and valve member 5 will cause the latter to stick sufliciently to its seat 3 to prevent any movement of the valve away from its seat under vertical agitation of the bottle, and yet will not be sufficient to cause said valve to remain seated when the pressure of liquid in the bottle comes against it as the bottle is inverted.

In order to prevent a refilling of the bottle by subjecting the same to a vacuum, which is a well known test of this type of bottle valves, the disk 8 is provided. In operation, when said disk and its stem 7 are forced through the cork piece 6 the air Patented July 27, 1920.

and aids in light enough in the interior chamber of the valve member 5 necessarily is confined. Now, when the bottle is subjected to a vacuum in a closed chamber, the differential of pressure created thereby will cause the stem 7 to be forced out of the cork piece '6, whereby the ball 17 will be forced against its seat 16, thereby retaining the valve member 5 firmly against its seat, and preventing any ingress of liquid into the bottle, and said disk 8 will remain in its projected position, effectually preventing any refilling until the members of the bottle valve are separated in dismantling the structure.

I have shown in Fig. 4 a slightly modified construction, wherein the disk 8 is dispensed with, the solid cork piece 19 operating in the same manner as does the disk 8' when the bottle is subjected to a vacuum, and forcing the ball '17 against its seat 16.

Vhile I contemplate employing any semiporous material from which to form the partial closure 2 and the valve member 5, still I have found that a magnesium compound constitutes the most advantageous material in that not only does it possess the necessary porosity, but also is of a weight properly to function as the valve member. V

The valve seat 3 being of porous material will permit air to pass through the same, thus preventing a vacuum from being formed inthe'bottle due to the expansion and contraction ofits contents under variations of temperature. 7 Y

The material of which I make the lower end 4 of the valve member Stand the partial closure 2 forming the valve seat 3 may be any semi-porous substance, such as unglazed pottery of any description, though I prefer to employ a substance known in the trade as magnesia ware now sold in the open market, the base of the same being magnesium, but which is understood to be manufactured under a secret process.

Having thus described myinvention, what I claim as new and desire to secure by Letters Patent, is

1. A'bottle valve, comprising a valve seat,

a-valve therefor having a broad area of contact therewith, said valve and seat being formed of semi-porous material of a character which when wetted will stick against movement under vibratory agitation of the bottle.

2, A bottle valve, comprising a valve seat, a valve therefor, and a retainer for'hold v 1ng said valve on its seat and having limited movement, said valve being adapted to ment, and a movable element in said valve adapted when subjected to a vacuum to move toward said retainer to wedge the latter in position, thereby preventing said valve from leaving its seat.

* 4. A. bottle valve, comprising a valve seat,

a hollow valve therefor, aretainer for holding said valve on lts seat and having limited movement, and a plug in said hollow valve upon which said retainer rests, said plug adapted when seated to cause a retention of air within said hollow valve, where'- by when said valve is subjected to a vacuum said retained air will force out said plug against said retainer and thereby lock 30 the parts with the valve in its closed position. H

5. The combination with a bottle; of a stopper disposed in the neck thereof and a pneumatically controlled valve in said stopper to prevent unauthorized refilling of the bottle. r

6. The combination with a bottle; of a stopper disposed in the neck thereof, avalve member movable in said stopper and having a fluid chamber therein, a pneumati cally controlled plunger slidable in said chamber, and means between said plunger and stopper to hold said valve normally closed, r Y

In testimony whereof, I hereunto set my hand this 5th day of December, 1916.

GILBERT JACKSON.
